Surround-view system
Surround view, also called as around view or birds-eye view, is a type of parking assistance system that uses multiple cameras to help drivers monitor their surroundings. It was first introduced in 2007 as the "Around View Monitor" parking assistance option for the Nissan Elgrand and Infiniti EX. == Principle == Early vehicle parking assistant products used ultrasonic parking sensors and/or a single rear-view camera to view and obtain distances to objects surrounding the vehicle, providing drivers with an audible alarm or rear-view video through a fisheye lens.
